Breaking change? Missing runTimeSecs in stats of the actor run

[honzajavorek]

I don't know where to file this, as it's probably a bug in the API, but I experience it through the SDK, so I guess this is the best place for me.

actor = client.actor(actor_name)
last_run = actor.last_run(status=ActorJobStatus.SUCCEEDED)
run_info = last_run.get()
if run_info is None:
    if raise_if_missing:
        raise RuntimeError(f"No successful runs of {actor_name!r} found")
    logger.error(f"No successful runs of {actor_name!r} found")
    return []
run_url = (
    f"https://console.apify.com/actors/{run_info['actId']}/runs/{run_info['id']}"
)
logger.debug(
    f"Last successful run of {actor_name}: {run_url}, "
    f"finished {run_info['finishedAt']}, "
    f"took {run_info['stats']['runTimeSecs']}s"
)
dataset = last_run.dataset()

This code has worked yesterday and it doesn't work today. I get

KeyError: 'runTimeSecs'

When I print what's in run_info, I get this:

{'id': 'DYdVuJJ3gZx0dp8wo', 'actId': 'hKByXkMQaC5Qt9UMN', 'userId': 'MdyLmQ25h82gno3Ab', 'startedAt': datetime.datetime(2025, 10, 30, 1, 11, 1, 10000, tzinfo=datetime.timezone.utc), 'finishedAt': datetime.datetime(2025, 10, 30, 1, 18, 14, 467000, tzinfo=datetime.timezone.utc), 'status': 'SUCCEEDED', 'meta': {'origin': 'SCHEDULER', 'scheduleId': 'RImSttfouf0jSbXoo', 'scheduledAct2Id': 'FqDKXTn0Dghx6JVEy', 'scheduledAt': datetime.datetime(2025, 10, 30, 1, 11, tzinfo=datetime.timezone.utc)}, 'stats': {'resurrectCount': 0, 'restartCount': 0, 'computeUnits': 0}, 'options': {'build': 'latest', 'timeoutSecs': 3600, 'memoryMbytes': 1024, 'maxItems': 173868, 'diskMbytes': 2048}, 'buildId': 'e1FCvitdLiTXeVtWO', 'exitCode': 0, 'defaultKeyValueStoreId': 'Pxeob9IkWb0J3LH3K', 'defaultDatasetId': 'ZlGrPg5kjoayN5XoH', 'defaultRequestQueueId': '4T1e4uKve9nFiZRgS', 'pricingInfo': {'pricingModel': 'PRICE_PER_DATASET_ITEM', 'reasonForChange': None, 'pricePerUnitUsd': 0.001, 'unitName': 'result', 'createdAt': datetime.datetime(2024, 8, 27, 13, 37, 42, 429000, tzinfo=datetime.timezone.utc), 'startedAt': datetime.datetime(2024, 8, 27, 13, 37, 42, 429000, tzinfo=datetime.timezone.utc), 'apifyMarginPercentage': 0.2, 'notifiedAboutChangeAt': datetime.datetime(2024, 8, 27, 13, 39, 17, 506000, tzinfo=datetime.timezone.utc)}, 'platformUsageBillingModel': 'DEVELOPER', 'generalAccess': 'FOLLOW_USER_SETTING', 'buildNumber': '1.0.114', 'containerUrl': 'https://rcfmcz3tn7nr.runs.apify.net', 'consoleUrl': 'https://console.apify.com/view/runs/DYdVuJJ3gZx0dp8wo'}

I guess the workaround is to do run_info['finishedAt'] - run_info['startedAt'], but the fact that the runTimeSecs is missing feels like an unintended or not well communicated breaking change. Maybe I'm just a victim of the Hyrum's Law? 😄

Hey @honzajavorek

runTimeSecs is an optional field - https://docs.apify.com/api/v2/act-runs-last-get#:~:text=Example%3A%20248472-,runTimeSecs,-number

As far as I know, the documentation and API schema have not changed. It is also optional in the SDK code.

Hi @honzajavorek, thanks for the report. The issue was on our API side and should now be resolved - the stats should be back. Sorry for the inconvenience.

@Mantisus Thanks for investigating! I thought it's optional only for runs which didn't finish. @vdusek Thanks for reporting the issue to the API team!
